Chute



Dec. 21, ,1943. s. E. WILLIAMS CHUTE Filed Aug. 7, 1943 2 Sheets-Sheet 2 .SamaeZZZrZ Md 5 AI 11's Patented Dec. 21, 1943 UNH'E'ED ":i" ES PATENT ()FFICE 3 Claims.

My invention relates to improvements in chutes for use especially, although not necessarily, in lowering pipe or tubing sections from an oil well rig to the ground, the principal object in view being to provide a simply constructed, strong and efiicient device of this character which is easy to install, ineXpensiVe to manufacture and replace, and will save time and labor in handling pipe or tubing sections at the well which are to be removed and stacked or otherwise disposed of.

Other and subordinate objects are also comprehended by my invention, all of which, toether with the precise nature of my improvements, will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in top plan of my improved chute,

Figure 2 is a view in bottom plan,

Figure 3 is a view in longitudinal section taken on the line 33 of Figure 1,

Figure 4 is a view in transvers section taken on the line 4-4 of Figure 1 and drawn to an enlarged scale, and

Figure 5 is a View in transverse section taken on the line 55 of Figure 3 and drawn to an enlarged scale.

Referring to the drawings by numerals, my improved chute, as illustrated, comprises an elongated member I provided at what constitutes the loading end thereof with an obtuse angled, flat, substantially rectangular extension 2 designed to be bolted, as at 3, to the platform 4 of a Well rig, not shown. At its other, or discharge, end, the member i is flattened and flared laterally to provide a widened, fiat extension thereon designed to rest upon th ground, or other base, and designated 5. Intermediate the ends thereof, said member is of substantially semi-circular cross-section, as shown in Figure 5, and is reinforced by external, transverse and longitudinal spiral ribs 6, l. The side edge of the member are beaded, as at 8, to provide longitudinal reinforcing external ribs along said edges.

A pair of substantially right angled bearing brackets 9 are provided at the loading end of the member I and which extend upwardly from the extension 2 and forwardly to opposite sides of said member. A shaft I0 is journaled at its opposite ends in anti-friction bearings l I mounted in the brackets 9, said shaft extending across the loading end of the member I and having suitably afilxed thereon a concave roller i2 disposed between the top and bottom of the member. As will now be seen, the member I is particularly adapted for attachment to the platform 4 to extend downwardly at an angle thereto with its discharge end resting flat on the ground or other base. In this position, pipe or tubin sections, not shown, as they are pulled out of the well and uncoupled, may be conveniently and easily tilted over the roller I2 into the member I to gravitate down the same for removal and stacking as desired.

The foregoing will, it is believed, sufilce to impart a clear understanding of my invention Without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right i herein reserved to such modifications as fall within the scop of the appended claims.

What I claim is:

1. A chute for attachment to an elevated platform or the like for unloading pipe sections therefrom comprising an elongated member of substantially semi-circular cross-section provided at one end with a fiat rectangular obtuse angled extension for overlying said platform, the other end of the member being laterally flared and fiattened to provide a widened discharge end thereon adapted to rest flat upon the ground.

2. A chute for attachment to an elevated platform or the like for unloading pipe sections therefrom comprising an elongated member of substantially semi-circular cross-section provided at one end with a flat rectangular obtuse angled extension for overlying said platform, the other end of the member being laterally flared and flattened to provide a widened discharge end thereon adapted to rest fiat upon the ground, and a concave roller extending across said one end and mounted thereon to lie between the top and bottom of the member.

3. A chute for attachment to an elevated platform or the like for unloading pipe sections therefrom comprising an elongated member of substantially semi-circular cross-section provided at one end with a flat rectangular obtuse angled extension for overlying said platform, the other end of the member being laterally flared and flattened to provide a widened discharge end thereon adapted to rest flat upon the ground, said member having reinforced side edges, and transverse and spiraled reinforcing ribs on the bottom of the member.
